An Efficient Asymmetric Synthesis of a Liquid Crystal

A synthesis of L-(-)-4-(2-methylbutyl)phenyl4'-(2-methylbutyl)biphenyl-4-carboxylate (CE2) and of related chiral liquid crystals has been reported; nevertheless, a detailed experimental and spectrometric characterization of both the intermediates and the final product has been lacking in the literature.We present here the first synthesis of the enantiomer of CE2 with full experimental details including spectroscopic data for each of the intermediates.The description of the synthesis of (R)-(+)-2-methylbutanyl will be broadly useful for preparing other liquid crystals with optically active (R)-2-methylbutyl side chains.

Phase Diagram and Preparation of CE2 Enantiomers

The synthesis of (L)-(-)-4"-(2-methylbutylphenyl) 4'-(2-methylbutyl)-4-biphenylcarboxylate (CE2) and related chiral liquid crystals has been discussed by Gray and McDonnell.We present here the first synthesis of the enantiomer of CE2 and we use it to measure the temperature-chirality phase diagram of the blue phases of CE2.This diagram is compared with that obtained using the CE2 "racemate" containing nonenantiomeric optical isomers of CE2.The synthesis of (R)-(+)-2-methylbutan-1-ol which has been developed will be broadly useful for the preparation of other chiral liquid crystals having optically active (R)-2-methylbutyl sidechains.

Liquid crystal compounds

Novel liquid crystal compounds are disclosed, which are chiral esters based upon the phenol STR1 Typical examples are: STR2 and mixtures of these compounds have a helical pitch such that the mixtures reflect light of a specific wavelength when illuminated with ordinary light and the pitch is temperature sensitive so that the mixtures can be used in temperature indicating devices. Specific examples are given as are samples of mixtures that can be used in phase change electro-optic display devices.
